2. "Artificial intelligence and machine learning" are closely related concepts. It can be said that machine learning is an important branch of artificial intelligence. Artificial intelligence is a subject that studies how to make computers intelligent. The purpose is to make computers think, make decisions and learn like people. Machine learning is a method to realize artificial intelligence. By letting the computer learn rules and patterns from the data, the algorithm and model are constantly optimized, and the ability to predict and judge unknown data is improved.
